Hey there!
I think you meant to type "value of what you own minus what you owe". Let me know if this assumption isn't correct, though I don't know what the value of what you owe is besides... ya know, what you owe.
The value of what you own is called you assets. This can include anything of value that you own, particularly your pricier possessions. Think of a vintage family heirloom or a highly–priced article of clothing. Assets, though, includes the value everything that you own that you could possibly put a price tag on if you were certain someone would buy it.
What you owe is called your liability. This is basically any debt that you owe anyone, whether it be your buddy who footed your lunch bill the other day when you didn't have enough cash or a student loan you used to pay for college.
Your assets minus your liability is called your net worth. This is basically what you are worth in total. This makes sense, since any debt you owe will be taken out of the amount that you are worth or any money that you have.
Net worth will be your answer.
Hope this helped you out! :-)
